Ordering random letters for a chance-random based TV gameshow.

Hello, everybody.

I will be pleased if I can get some help to solve this problem :

I have 50 cells (let's say A1 to AX1) with (3 x letter G) + (19 x letter V) + (28 x letter R) in random positions.
like in the attached file.

I would like to "read" the cells from left to right and know :

- Where is located the first V, starting from any cell ?
- Where is located the second V, starting from the same cell ?
- Is there any G between the starting cell and the second V ?
- If yes, how many ?

Example in the attached sheet :

- The first V after AA1 is AF1
- The second V after AA1 is AH1
- Yes, there are 2 G between AA1 and AH1

This (maybe) unusual inquiry is to solve a chance-random based TV gameshow under development.

Thanks a lot for the kind help.
Best.
